Abstract

The invention discloses an imaging method and device based on spatial coding, the imaging method is realized through an imaging device, the imaging device comprises a camera, a projector and a processor, the projector is a color laser projector, and the imaging method comprises the following steps: the processor calibrates the camera and the projector; wherein the projector projects a preset image, and the preset image respectively projects sine wave structured light and a spatial coding image through a monochromatic laser in the projector; analyzing the mixed image is analyzed to obtain sine wave structured light data and spatial coding data; the processor obtains the absolute phase shift of the sine wave structured light; wherein the projector projects sine wave structured light on a target object; the camera shoots an object image of the target object projected by the sine wave structured light; and the processor obtains a three-dimensional model of the target object according to the absolute phase shift of the sine wave structured light and the object image. The method has the advantages that the operation speed is high, the time for obtaining the model of the object is short, and the model precision is high.

Description

technical field [0001] The invention relates to an imaging method and device based on spatial coding. Background technique [0002] Three-dimensional reconstruction refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects. It is the basis for processing, operating and analyzing its properties in a computer environment, and it is also a key technology for establishing a virtual reality that expresses the objective world in a computer. [0003] Three-dimensional reconstruction by grating projection is a three-dimensional reconstruction method. The grating is projected onto the reference plane and the surface of the measured object respectively. Since the reference plane is a horizontal plane, the reference grating projected on it will not be deformed; when the grating is projected onto the measured object When measuring the surface of an object, the grating will have different degrees of deformation, b...
